View 1 RepliesVB 2008 .suo File Needs To Be Changed/recreated Because A Path Has Changed. All Other Files Are OK
May 5, 2012I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?
.NET SQL Date Is Changed Format In Query?
Apr 6, 2010I've got a date variable that looks like this:
Dim LogDate As Date = Date.Today.AddDays(-1)the format comes out like: #4/5/2010#
then it goes into a SQL select query as a WHERE clause. When I debug, the query has changed this to '05/04/2010'. I want it to be in the format '04/05/2010' like it is when declared. Any ideas on how I do this?
Hee is the query: Dim sqlCmd As New SqlCommand("SELECT TOP (100) PERCENT tblBackup.BackupName,
tblBackupArchive.BackupDate, tblStatus.Status FROM tblStatus INNER JOIN tblBackupArchive ON
tblStatus.StatusID = tblBackupArchive.StatusID INNER JOIN tblBackup ON tblBackupArchive.BackupID =
tblBackup.BackupID INNER JOIN tblClient ON tblBackup.ClientID = tblClient.ClientID WHERE tblBackupArchive.BackupDate = '" & LogDate & "' AND (tblBackupArchive.StatusID = 3) ORDER BY

Sql Filestream - Update A File And Save Changed File Back To Database
Oct 30, 2009I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]
Saving Changed Data Before DataViewGrid Selection (Row) Changed?
Jan 20, 2010on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

File I/O And Registry :: FileSystemWatcher.Changed Not Triggering
Mar 6, 2009[URL]
I'm using FileSystemWatcher to monitor a file on a windows server which links into a news ticker on our desktops. The ticker watches the file and updates accordingly. I've successfully got the ticker to watch for a creation and deletion which is great but the changed function doesn't seem to trigger. Out of interest, I tried this function on the network drive AND a local disk with the same results.
I've upped the buffer but I can't see what else I can do to change it! In the short term, we can probably live with just deleting and recreating the file with any changes that are required, but it would be nice if the ticker would just watch for file changes.

View 20 RepliesDeleting Records From A LstBox And Dat File And Setting Reminders To Date In Dat File
Aug 2, 2010I am creating a program that allows a person to enter details about their farm, stock, and machinery in order to electronically keep track of all of the information. I have created the forms and done all the coding for the data entry, and now what I would like to do is allow the user to delete a single record from the .dat file. I am able to delete it from the LstBox (using a "Delete Entry" btn coded simply with
lstvehicles.Items.RemoveAt(lstvehicles.SelectedIndex)

Also I would like to be able to have a reminder come up on the program start up that gives a reminder to (in the vehicles instance)when a vehicles rego is due, the date being associated to a date that is entered into the same lstbox data using a datetimepicker.
File I/O And Registry :: FileStream File Creation With Date?
Apr 16, 2009I have found many pages referring to having the date be part of a txt file being created, but not like the way I need. Having said that, this is what I've got.. [code] I read a page on working with txt files and learned what I could from it. It said to use the method in the beginning of my code for creating the file. It works great, but I would like to have a new file name everday, hence the date being integrated. So even if program was running, when midnight hits, a new txt file is created and new entries are written to that file. But I can't even get the date to be put in there. Everytime I try to make this work by using methods I read about in other pages, I get a syntax error, or a warning saying an end of statement is expected. I'm not sure those methods are compatible with what I've already got going.I was actually trying to store these values in a database, and I got real close I think, but I couldn't get any help to fix my problem so I'm trying to write to daily txt files instead. url....

.net - Get File Modified Date
Sep 8, 2010I have a number of files in a folder, I need to get the last modified date. So I used FDate = IO.File.GetLastWriteTime(FName) Works fine with some files, but on others, I get a date of 1/1/1601. But when I check the files in Windows Explorer, all the dates look normal (recent). So, I'm gessing there are multiple files dates stored in the file system, and the ones dotnet is seeing are not the ones windows is seeing. How can I get exactly the date which appears as "date modified" in a file explorer window? I tried some vb6 api stuff but that doesn't seem to work in dotnet.

Determine If Row In File Is Date
Jun 13, 2011When scanning a data file of this kind of form:
21/02/11 11:00:23, true, false
22/02/11 02:03:43 AM, true, false
22/03/11, false, false
2011-05-21T12:30:20, true, true
The 2nd and 3rd row are not important. How can you, by scanning a file, determine if a row comprises of dates, particularly when they have inconsistent formats? In the example above, for instance:
1) 1st line is date and time
2) 2nd line is date and time but also AM/PM
3) 3rd line is only date
4) 4th line is GMT format.
I'm not requesting code, but perhaps an algorithm or some guidelines on how to achieve this.

Adding A Date In A Text File?
Jun 8, 2011I have a program i wrote today, it works just as i wanted it to, with exception of one problem. Im more looking for some ideas on this one. For my work, we have folders on a drive that are filled with txt files, what we wanted to do was to add the last date it was modified to the top of the file so people would know when it was last modified. These files are used on CNC machines and the those people cant look at a last modified date as easy as the computer user can, just a short explanation of why we wanted to do this. So i wrote a program to do it, loop through each file in the user selected folder and add a date to the top of it, works perfect. Now here is the issue, when i write the last mod date to that file, the last mod date on the file changes to that day. For example, if i have a file in there that was modified January 28th 2011, the program reads that file, then on the top of the file it prints that date, January 28th 2011, but then that same file gets changed to the current date as a modified date, so if the program i wrote is used again on the same folder the next day, those files will all end up getting the previous days date on the top. I dont want that! I guess im wondering if there is a way to tell the files mod date not to get updated when its run through my program, it should only update when changed some other way, like someone actually opens it, changes stuff and hits the save button.
